Resumen de: AU2023360141A1

With the wide usage of Li-ion batteries (LIBs), recycling and reusing LIBs have attracted wide attention. However, due to the low added value and rigorous separation steps, recycling and recovering graphite anode materials are discarded. Although some direct physical recycling processes have been reported, all of them are limited by rigorous separation steps and lab scales. The present invention relates to a method for recovering highly pure graphite from leach residue of spent lithium ion batteries. The process is simple, easy and provides 99.9% pure graphite. Additionally, the method for recovering highly pure graphite is clean, green, environment friendly and commercially feasible.
